How is GetHashCode() implemented for Int32?

问题

I've been looking all over the place, but I can't find anything. Can anyone shed some light on this?

回答1:

According to Reflector:

public override int GetHashCode()
{
    return this;
}

Makes sense, does it?

回答2:

Best way to hash 32 bit value to 32 bit is not to invent wheel, use value itself. Very fast, no collisions, indeed a perfect way.
